Trump Tariffs Against China Take Effect by Associated Press WASHINGTON -- U.S. tariffs against Chinese imports took effect early Friday and President Donald Trump made clear Thursday that he is prepared to sharply escalate a trade war between the world's two biggest economies. The administration started imposing tariffs at 12:01 a.m. Eastern time Friday on $34 billion worth of Chinese imports, a first step in what could become an accelerating series of tariffs. China has promised a swift retaliatory strike on an equal amount of U.S. goods. Trump discussed the trade war Thursday with journalists who flew with him to Montana for a campaign rally. The president said U.S. tariffs on an additional $16 billion in Chinese goods are set to take effect in two weeks. After that, the hostilities could intensify: Trump said the U.S. is ready to target an additional $200 billion in Chinese imports -- and then $300 billion more -- if Beijing refuses to yield to U.S. demands and continues to retaliate. That would bring the total of targeted Chinese goods to potentially $550 billion, which is more than the $506 billion in goods that China actually shipped to the United States last year. The Trump administration has argued that China has deployed predatory tactics in a push to overtake U.S. technological dominance. These tactics include cyber-theft as well as requiring American companies to hand over technology in exchange for access to China's market.
